IMO most Hermes SA are not friendly or approachable at all, they seem to think they have the upper hand and the brand is always in high demand so more clients will buy their goods even if the customer service is below par. That’s Hermes, many clients suck it up hoping to be offered a bag. If you’re lucky you’ll come across a nice SA at the store. With Hermes it’s all about relationship, but I do think it goes both ways.
Nowadays I prefer to shop online so I don’t have to deal with unpleasant/snobbish SA. Let’s just say that if you shop different brands you will be treated in a much nicer way than H.
Best of luck
